Rivers and coasts Starter activity:

Rivers and coasts• Learning objectives:– All to know key terms of the advanced hydrological

cycle– Most to be able to separate terms into stores and

flows, inputs and outputs– Some to start to link the hydrological cycle to how it

might affect people and their lives

• Key terms/literacy focus today: Hydrological key terms

• Your starter questions?

The Hydrological cycle

Why should we bother learning about this?

Let’s see at the end of the lesson.

Key term Definition Key term Definition

Evaporation Water slowly seeping into the bedrock

Precipitation Water moves towards the sea through rivers and streams

Groundwater flow The movement of water over the surface of the ground

Channel flow Water soaks into the soil layer

Percolation Water falling from the sky as rain, hail, sleet and snow

Infiltration The very slow movement of water through the bedrock

Evapotranspiration Precipitation is prevented from reaching the ground by leaves

Overland flow Water evaporates from the leaves of plants back into the atmosphere

Throughflow Water changes state from a liquid to a gas

Interception Water moving through the soil layer

Condensation Water changes state from a gas to a liquid

With a partner, match up the definition to the key term on your printed copies.

The hydrological cycle

In pairs, allocate the correct key terms and definitions to each letter on your printed copy of the diagram to fully describe

and explain the hydrological cycle

The Hydrological Cycle

• Extension – colour code and label extra areas on your diagram labels to show the following:– Inputs to the hydrological cycle/system– Outputs from the hydrological cycle/system– Stores where water resides for significant

amounts of time– Flows where water moves between stores

How could this affect humans?

• Linking back to slide 3, let’s start to think about how this could affect people (and therefore why we bother studying it).

• Examine your diagram. Identify areas where you think people’s lives could be affected & add an annotation to explain how this could work. Example?
